have iniented certain new and. useful Improvements in Antislipping Devices for "j Power-Driven-Vehicle Vheels, of which the "'following is aspeci fication. i "1e 1, Thisinven'tion relates more especially to automobile "whels',"the primary 0b]ect being toproi-ide a pavement gripping means that not carried "on" the tread of the wheel.

shown this improved device is provided with an outer annulus 6 and inner annulus 7. A series ofbrackets 8 are secured to the annulus 6 and arranged radially therearoundl Said brackets have afiat horizontal portion t) which is adapted to be seated against the inner surface of the telly 3, and tobe se cured thereto by the bolts 10. The'annulus 7 has secured thereto on one side thereof a right-angle portion 11 which is adapted to fit against one side of the spokes 4t, and is secured thereto by bolts 12. It is preferable to secure the annuli 6 and 7' together by aseries' of ribs 13 so that they will always aline with one another. 2

Radially arranged around the periphery of the annulus 6 are a series ofbearing blocks 14. Each block 14 has formed theren an opening l5. Each of said openings 15 is adapted to'be in radial alinement with openings 16 formed in the annulus 7 a Reciprocally mounted in each pair of openings 15 and 16 are pavement gripping fingers 17. The outer ends 18, which are adapted to en gage the pavement, can be pointed or otherresults. Y

. Formed on theinner end of each finger 17 "is a rounded head 19-which is adapted to en.

gage the concave surface 20 of'an engaging 8 shoe 21. I Secured to each finger 17 and positioned thereon between the annuli 6 and "Z, are washers 22. Mounted on said fingers on each side of said washers 22 are springs 23 and 24.

Mounted on the under side of the housing 25 of the axle 26 area pair of shoes 27," forming part of a horizontal plate 28. Said plate has formed thereon, and depending therefromat one end, a pair of vertical beatare mounted a pair of 3 Said 'guideg-rrods ertic'al 'guiiding -.e;\*tencl ;upwar and on 1hr side oi teld on guljd, -the s ngs} erends 0i 6 hfli :yg 'r" if; C Mounted over the housing 25, and secured at their lower ends by nuts 34 to the plate'28,-are a pairof U-bolts '35. Secured to the shoe 21, and on the inside of the guides 30, are a pair of upstanding brackets 36, the upper ends thereof being bifurcated for the purpose'of holding one end of a pain of leaf springs 37. Each of said leaf springs has secured thereto 'a roller 38,

which rollers are adapted to "bear against the under sideof the plate 28. Secured to theopposite end of each spring 37 is.a cable connection 39 to which is secureda cable 40. It is to be understood that an improved device of this vcharacteris to be mounted on the inside of each rear wheel, the parts b e-' ing identical.

There will, therefore, be a pair of cables 40 which will lead on up to the point adjacent the operator, and will be connected to some lever movementnot V shown.

In the operation of this improved device,

when applied to a pair of'vehiclewheels, if it is not necessary to apply gripping means to the pavement, lthe. operable parts assume their position as shown in full'lines in .the

drawings. But when it is desired toengage the gripping fingers 17 against the surface of the'paveinent or roadway, power is applied 'to the cables 40, and movement is given to the springs 37. Said springs having the requi- "site stiffness and resiliency, andbeingpivoted at 4:1 to the rollers 38, a downward pressure will be applied to the brackets 36, thereby carrying the engaging shoe. 21 downwardly. This downward movement will carry the said shoe into engaging alinement with the heads 19 of the fingers 17.

Said fingers 17 are. carried by the wheel, and as. they pass-under the concave surface 20 of said shoe, they'will be depressed until the outer ends 18 thereof come in contact with the pavement. As the wheelcontinues to rotate and the points are carried around,

- theheads 19 will ride from under the concave surface 20 of the shoe 21. The springs 24.--of each finger engaging against the an- ,n'ulus and their respective washers 22,,

wilhcdrry said fingers to their normal, or idle, position. So: long as the engaging shoe; 21 is. depressed, said engaging fingers,

as their heads 19 engagesaid shoe, will be pressed. downwardly in contact with the pavement. \Vhen this gripping function is no longerrequ1red,,.the.cable 40 is released .and the springs '31, mounted on the guides 30,w ill elevate the shoe 21 to its normal position. Then the fingers 17 will discontinue fengaging the pavement. If obstacles on the roadway are encountered by the 'ends 18 ofg the fingers 17, which'will not allow said fingers to come in contact with the' roadway, the shoe 21 will be forced up war'dly against the pressure of the springs 37. .The springs 23 mounted on the fingers 17 merely serve as cushion springs after 1 said fingers have been released from the shoe 21.

a vehicle, equipped with this improved device, is traveling over country roads, shoes 42 having a largecontacting surface, such as shown in Fig.- 4, canbe mounted on the outer ends 18 of the fingers 17, and be held by. the set screws 43." I

.-In order to holdthe rollers 38 of the springs 37 against the under side of the plate 28, a fiat horizontal leaf spring i4 is secured to the under side of said pla'te 28 for engagement with the pivot 4:1 Of said rollers.

' hat I claim is:

1. In an antislipping device for a'vehicle wheel, a frame carried by said wheel, a series of fingers carried by said frame adapted to reciprocate therein, a shoe for engagement with said fingers, and a pivotally mounted resilient member having a said leaf spring being pivo'tally mounted to a roller, said roller bearing against said plate, said'leaf spring when actuated on its pivot adapted to engage said shoe against one end of said fingers.

3. 'In an antislipping device for a vehicle wheel, a frame carried by said wheel, a series of fingers carried by said frame adapted to reciprocate therein, and a shoe for engagement with said fingers and a leaf spring for engaging. said shoe against said fingers.

4. In an antislipping device for a vehicle wheel, a frame carried by said wheel,:a series of pins reciprocably mounted therein, it

movable shoe for engagement with said pins and a pivotally mounted. leaf spring for engaging said shoe against saidfingers.

' 5. In an antislipping device for a vehicle Wheel, a frame carried by said wheel, a series of pins reciprocably mounted therein, a movable shoe for engagement with said pins a pivot-ally mounted leaf spring for actuating said shoe, said shoe adapted to move said fingers outwardly.
